CROSS-HEAD CONNECTION.

To all whom it may concern Be it known that I, GEORGE G. BLoNDo, acitizen of theUnited States, residing at Fairbanks, in the county ofCochise and Territory of Alaska, have invented certain new and usefulImprovements in Cross- Head Connections, of which the following,

is a specification. v

My invention relates to improvements in connections for crosshead slidegibs, pitman or like constructions; and the main object of my inventionis the provision of a simple, inexpensive, durable and throughlyeiiicient means for providing a connection which can be easily applied,which will retain the parts in proper position; and which will i providefor taking up wear between the parts.

With this object in view, my invention consists of means of thecharacter and for the purpose stated embodying novel features ofconstruction and combination of parts, substantially as shown, describedand claimed.

Figure 1 is a top plan view of the connecting plate forming the mainfeature of my invention. Fig. 2 represents an edge view thereof. Fig. 3represents a'perspective view of" the securing pin or Wedge. Fig. lrepresents a detail view showing the invention applied to a crossheadand its member for reciprocating said crosshead. Fig. 5 represents adetail sectional View showing the manner of inserting buildingup or wearstrips, and Fig. 6 represents a perspective view of one of thebuilding-up strips. I

In the drawings: the numeral 1 designates the crosshead, which issecured to a movable or slidable member, and fitted to said crosshead isthe arm 2, formed with a recess 3, for sliding upon said crosshead. Thepurpose of my invention is to connect this arm to the crosshead; and mydevice consists of the plate 4:, which fits in the recess of the armbetween the arm and cross head; and said plate at one end is formed witha shoulder 5, which engages one edge of the arm, and at its other end isformed with a shoulder 6, which engages the opposite edge of said arm.The shoulder 6 being provided with a channel or cavity 7 Specificationof Letters Patent.

strip retains the arm rigidly in position between the shoulders and inproper rela tion to the plate and crosshead. In the event of wearbetween the arm and plate, I use one or more of the strips 9, whichserve to take up any wear between the plate and arm, and thus provide arigid connection which compensates for all wear or friction between theparts.

It will beunderstood that a device of this character maybe used for manypurposes, and that it will perform the function for which it is intendedin a thorough and If desired, 1 may use a fiat-spring 10, in place ofstrips 9.

I claim:

1. In combination with a sliding cross head, a pitman receiving armfitting upon said cross head, a plate fitting between the cross head andarm and having a fiat hook at one end and a recessed hook at its otherend, and a wedge strip fitting in the recessed hook and bearing againstone facehook at one end and a recessed hook at its other end, a wedgestrip fitting. in the recessed hook and bearing against one face of saidarm and having a hook at each end to engage said plate to retain thewedge strip in position, and means arranged between said wedge strip andrecess of said hooked arm to take up wear upon said strips.

In testimony whereof I aflix. my signature in presence of two witnesses.
